AIR REGISTER.

' Application filed January '13, 1923." Serial No. 612,367.

i'Ihis'invention' relates to air registers for admitting and controlling the delivery of air around a conical spray of liquid orjiinely divided fuel and more particularly for use with atomizers whichhavea wide range incapacity and has for its object the produc- ,vide a cylindricalopening 31 in which my .tion of an air register of simple and cheap construction that will admit air to a boiler with the least possible confusion so that an intimate mixture of air and oil will be main- A further object-is to provide a register that: will hold the flame to the burner and prevent pulsations commontooil burning furnaces. I

The; foregoing and-other features of my invention willnow lie-described in connecing part of this specification in which I have represented its applications after which ;I- shall ponit out in the claims those features which I believe to be new and of my own invention;

In the drawings: 7

Figure 1 is a vertical cross section of my air register.

Figure 2 is a top plan View of same show-' ing the controlling means which operates the shutter. I V

Figure 3 is a front .view thereof.

In the carrying out. of my invention the furnaceor combustion chamber is shown at 1 with an opening 2. In the opening 2 I provide an annular ring 3 provided with extensions ,4 having a projecting guideway 5 on the inner sides thereof. t

Coaxial with the annular'ring 3 I provide a shutter 6 adapted to slide upon the projecting guides 5.

In suitable bearings 7 attached to the shutter'6 is mounted a shaft 8 provided on each end with mutilated gears 9 adapted to engage racks 10 on the extensions 4:. A handle 11 is provided to rock the mutilated ears its seat which is the annular ring 3.

The spray nozzle 21 may be of any well known type powdered fuel into the combustion chamber and is provided with an inlet tube 22 which is held in position by the supporting bar 23. In Figure 3 I illustrate the bar'23 attached my air register in one of and move the shutter 6 to and from for injecting either liquid or to the shutter 6; by the bolts24. Withthis construction the burner, diifuser, and the I shutter all move when the gears 9 are rocked uponthe racks 10' as will be readilyunderstood. On the inner part of my shutter 6 I pro-.

diffuser 32 is adapted to telescopically slide. This diffuser is cylindrical in shape with a restricted end 33 somewhat largerthan the tube 22 of the atomizer to be used, so that a small amount of air can enter around the atomizer. This diffuser 1S constructed with .a sharpdropat the restricted end and does not in any manner reduce gradually or reused.

Attached to the difiuser is a handle 34 which projects through the supporting bar 23, by means of which the position of the diffuser with respect to the atomizer2l may be adjusted at will, and the air entering around the atomizer may be regulated or Deflector plates 41 held together by spacers 12 and secured to the shutter 6 by the bolts 43 are used to radiate theheat from the furnace and to preheat the air entering through the register openings.

I wish it dist-inctlyunderstood that my air register herein described and illustrated is in the form in which I desire to construct it and that changes or variations may be made as may be convenient or desirable without departing from the salient features of my invention and I therefore intend the following claims to cover such modifications as naturally fall within the lines of invention.

I claim:

1. An air register comprising an annular ring adapted to fit an opening in a furnace .semble the conical diffusers now generally 1 front, outwardly extending guides carried thereby, a frusto-conical shutter slidably mounted in said guides, means for admitting air through said shutter and means for mov ing the shutter toward and from the furnace front opening.

2. An air register coinprisingan annular ring adapted to fit an opening in a furnace front, outwardly extending guides carried thereby, a frusto-conical shutter slid-ably mounted in said guides, means for admitting air through said ifluitter and a cylindrical difliuser mounted in said sl'iutter.

3. An air register comprising' an annular ring adapted to fit an opening in a furnace front, outwardly extending guides carried thereby, a frusto-coniral shutter slidably mounted in said guides, an atomizer, and a cylindrical diffuser mounted in said shutter and. having a reduced portion surrmrnding thentomizer.

4. An air register crnnprising an annular ring adapted to fit an opening in a furnace front, a frusto-conical shutter nimmbly supported by said ring an atomizer. and a cylindrical diffuser mounted in said shutter and surrounding said atomizer.

An air register comprising an aniu'llnr ring adapted to fitan opening in a iurnmre front, It fiustwconicul shutter movably supported by said ring; an atomizer a cylindricaldifluser surroundingsaid atomizer, and a portedbysaid shutter.

S. An air-register comprising anannnlar ring adapted to fit an opening in a furnaceseries of deflector plates supported by said shutter. i

6. An air register comprising an annular ring adapted to fit an opening in a furnace front, a frnsto-conieal shutter niovabl'y ported by said ring, a support cari edby said shutter". an atomizer i'nountod in said support and a cylindrical diffuser mounted in said shutter and having a reduced portion surronndi in); said a tomice r.

T.
